## Kinetic Friction

### To calculate Kinetic Friction:

The force of friction calculator offers all types of kinetic friction calculations. By using this frictional force calculator, you will be able to calculate:

- Kinetic Friction (Fk)
- Kinetic friction coefficient (μk)
- Normal force (N)

If you want to learn this topic thoroughly, continue reading. We are going to explain how to find force** **without using the kinetic coefficient of friction calculator, equation for friction, kinetic friction definition, coefficient of friction formula, how to find frictional force, and much more in this space.

## What is kinetic friction?

When two objects moving along each other and rubbing one another, they are subjected to kinetic friction. It is a force that exists between moving surfaces. The kinetic friction coefficient is denoted as ** μk. **The unit of friction is Newton

*N.*The force between two non-moving objects is called static friction. Static friction is always greater than kinetic friction. Calculator School offers both static and kinetic friction calculators.

## Kinetic friction formula

Kinetic friction equation or friction force equation can be expressed as:

**F _{k}= μ_{k} η**

Where,

** F_{k}** represents the force of kinetic friction,

** η** is the normal force, and

** μ_{k}** refers to the coefficient of kinetic friction.

## How to calculate friction?

Wondering** **how to find coefficient of friction** **without using a kinetic friction force calculator?** **Here, we will explain the step by step method to find friction.

**Example:**

If a table with a weight of ** 20 kg** is being pushed on the floor with a coefficient of friction of

**find the**

*0.30,**total*

*kinetic friction*between the table and the floor?

**Solution:**

**Step 1: **Identify and write down the values.

*Mass (m) = 20 kg*

*μ _{k} = 0.30*

**Step 2: **Use the force of friction equation** **and place the values.

**F _{k}= μ_{k} η**

Since ** η **represents the force. We can use the equation of force

**to replace the**

*F = mg***.**

*η***F _{k}= μ_{k} mg **

**F _{k}= 0.30 × 20 kg ×9.81 m/s^{2} ∴ g = 9.81 m/s^{2}**

**F _{k} = 58.86 N**

Use the force of kinetic friction calculator** **above to authenticate the answer in this example.
